Title:
Search for a heavy gauge boson decaying to a charged lepton and a neutrino in 1 fb-1 of pp collisions at sqrt(s) = 7 TeV using the ATLAS detector

Abstract: The ATLAS detector at the LHC is used to search for high-mass states, such as
heavy charged gauge bosons (W'), decaying to a charged lepton (electron or
muon) and a neutrino. Results are presented based on the analysis of pp
collisions at a center-of-mass energy of 7 TeV corresponding to an integrated
luminosity of 1.04 fb^-1. No excess beyond Standard Model expectations is
observed. A W' with Sequential Standard Model couplings is excluded at the 95%
confidence level for masses up to 2.15 TeV.
